Update: Both bugs are still present in the functionality of ChoralNet. The "broken links" bug appear to only be happening in blog posts. In today's blog post ("Eric Whitacre and the standing ovation from TED 2011"), the link in the first sentence is broken.

Update#2: It appears that the second bug listed above (broken links in blogs) has been fixed, although the links haven't yet been fixed in the posts made during the problem. I haven't heard any updates on the problems with the login/remembering system, but I'm confident that it's being worked on.
